Background technology
In recent years, slide fastener is also installed on the clothes of various softness, requires that the situation of flexibility increases to zipper strip itself.Therefore, the various zipper strips be compiled to being imbued with flexibility compared with fabric are developed.Especially from the view point of possessing flexibility and the excellent in stability of form is such, the zipper strip with warp knitting fabrics is widely used gradually.
In addition, synthetic resin system or metal chain tooth are being formed in zipper strip, when formation zip strip, metal chain tooth riveted joint is being fixed on zipper strip, the situation forming zip strip is inferior, in order to improve the installation strength of chain tooth relative to zipper strip, generally at the tooth installation portion configuration core rope of zipper strip.Especially, as described above, when core rope being configured in the tooth installation portion of the zipper strip with warp knitting fabrics, core rope, while weaving into zipper strip, is incorporated into tooth installation portion.
Relevant have warp knitting fabrics like this, and the example of enrolling the zipper strip of core rope at tooth installation portion is as open by Japanese Unexamined Patent Publication 55-148409 publication (patent document 1), Japanese Unexamined Patent Publication 8-56713 publication (patent document 2).
Above-mentioned patent document 1 discloses to be weaved into by single-row pin, enrolls the zipper strip of core rope at tooth installation portion.This zipper strip uses chain type litzendraht wire, Trico litzendraht wire and single sley bar to organize different litzendraht wires to weave into through suede litzendraht wire three kinds, core rope be inserted into and the single sley bar being incorporated into tooth installation portion through between suede litzendraht wire and two sinker loops of Trico litzendraht wire.
In addition, according to this zipper strip, use hook as single sley bar through suede litzendraht wire, make the warp tension ratio list sley bar of Trico litzendraht wire large through the tension force of suede litzendraht wire.Accordingly, owing to producing Tension Difference at the sinker loop of Trico litzendraht wire and single sley bar between the sinker loop of suede litzendraht wire, so core rope is pushed to single sley bar through suede litzendraht wire side, the shape of heaving of enrolling the part of core rope becomes object inside the table of zipper strip.
Therefore, it is possible to when metal chain tooth being assembled to this zipper strip by riveted joint, prevent the installation site of chain tooth from staggering from the central part in direction (zipper strip thickness direction) zipper strip table.
Above-mentioned patent document 2 describes by possessing prostatitis pin and rank rear pin, and the zipper strip that machine is weaved into is compiled on the double two sides can weaving into backed weave by carrying out weaving into respective pin.The tooth installation portion that this zipper strip has zipper strip main part, the central part in direction is configured with core rope in zipper strip table.The zipper strip main part of this zipper strip is weaved into by rank rear pin, and the ground tissue of this zipper strip main part is made up of chain type litzendraht wire, Trico litzendraht wire and the first laterally inserted line of being inserted into zigzag between four wales.
On the other hand, the tooth installation portion of this zipper strip is weaved into by backed weave.In addition, this tooth installation portion has two row wales, between these two row wales, configure core rope.In addition, the knit stitches of this tooth installation portion is by the chain type litzendraht wire be compiled in zipper strip table and be inserted into zigzag between two wales, and the two second laterally inserted lines configured symmetrically in zipper strip table are formed, core rope is configured between two second laterally inserted lines, and two second laterally inserted lines are configured in zipper strip table.

Invention effect
In slide fastener for the present invention, zipper strip is made up of warp knitting fabrics, while carrying out the weaving into of zipper strip, enrolls core rope at tooth installation portion.Zipper strip main part has the first zipper strip main part region of the side edge part being configured in tooth installation portion side and is configured to the second zipper strip main part region of another lateral margin of zipper strip main part from the wale with this first zipper strip main part area adjacency always.In addition, and the wale of the tooth installation portion of the first zipper strip main part area adjacency and form the first zipper strip main part region wale between respective wale interval and the second zipper strip main part region wale interval compared with by constriction.
Zipper strip of the present invention so stably can guarantee the flexibility in the second zipper strip main part region, and make with the wale of the tooth installation portion of the first zipper strip main part area adjacency and to form the wale in the first zipper strip main part region close to each other, the region of the zipper strip main part side of tooth installation portion and the line density in the first zipper strip main part region are increased.Accordingly, zipper strip intensity and the mar proof in this zipper strip region can be improved easily.
Have again, zipper strip of the present invention is owing to can improve the line density in above-mentioned zipper strip region, so, such as when tooth installation portion forms plastic chain tooth by injection molded, when forming metal chain tooth by casting forming, effectively can prevent from producing fused mass from the coil of tooth installation portion to leak, the quality, the raising yield rate that improve slide fastener can be sought.
Especially in zipper strip of the present invention, the thermal contraction line possessing heat-shrinkable is configured in and the wale of the tooth installation portion of the first zipper strip main part area adjacency and the wale being formed the first zipper strip main part region to cross over the above mode of two row, and the percent thermal shrinkage of thermal contraction line sets higher than the line being configured in the wale in formation second zipper strip main part region in the mode of crossing over the above wale of two row.Accordingly, utilize the thermal contraction of above-mentioned thermal contraction line, positively the wale of the tooth installation portion of constriction and the first zipper strip main part area adjacency and the wale interval that forms in the wale in the first zipper strip main part region.
Therefore, in zipper strip of the present invention, there is not the situation that the interval (interval namely, between the first and second wale) between the wale such as forming tooth installation portion as above-mentioned patent document 3 expands.Therefore, it is possible to core rope stably to be remained on the assigned position of tooth installation portion, position and the stable posture of the chain tooth being assembled in tooth installation portion can be made.
In addition, even if after the online thermal contraction of the comparison of the percent thermal shrinkage of line, such as, also can the heat stagnation of these lines by inquiry carry out afterwards.Specifically, the thermal stress of line is investigated.Namely, by being determined in manufacturing engineering because being applied to the temperature, tension force etc. of line and the strain of accumulating on line, can estimate apply in this manufacturing engineering temperature, tension force delayed, can from the height of the percent thermal shrinkage of the delayed alternative line of the temperature of this presumption, tension force.
In such zipper strip of the present invention, form one of lines as it, comprise crossing over the first laterally inserted line inserting above-mentioned wale with the wale of the tooth installation portion of the first zipper strip main part area adjacency and the mode of at least two row wales of tooth installation portion side that is configured in the first zipper strip main part region.By having the first so laterally inserted line as thermal contraction line, can make tooth installation portion and the first zipper strip main part area adjacency wale and be configured in the first zipper strip main part region tooth installation portion side two row wales between wale interval constriction effectively.
In this case, as one of the formation lines of zipper strip, except the first laterally inserted line, include as on the wale being configured in the tooth installation portion of leap first zipper strip main part area adjacency of thermal contraction line and the above wale of two row forming in the wale in the first zipper strip main part region, be inserted in the first laterally inserted line and coil walk crosswise between the second laterally inserted line in the direction intersected.
Accordingly, constriction the wale interval in the zipper strip region of the first and second laterally inserted line can be configured more effectively.In addition, can make to configure and shrink at zipper strip length direction with the zipper strip region of the wale of the tooth installation portion of the first zipper strip main part area adjacency and the wale that forms the first zipper strip main part region, the line density in this zipper strip region is increased further.
In addition, by one of formation lines as zipper strip, the longitudinal direction also comprising each wale being inserted into formation first zipper strip main part region inserts line, the line density in the first zipper strip main part region can be made to increase further, the zipper strip intensity in this region and mar proof are improved further.
In addition, in the present invention, as one of the formation lines of zipper strip, except the first laterally inserted line, also can comprise and cross over the wale of the tooth installation portion of the first zipper strip main part area adjacency and form three in the wale in the first zipper strip main part region and arrange first and second single sley bar that above wale is inserted into through suede litzendraht wire.
By configuring first and second so single sley bar through suede litzendraht wire, also wale interval constriction can be made effectively, and can make to configure the first laterally inserted line and first and second single sley bar shrinks at zipper strip length direction through the zipper strip region of suede litzendraht wire, increase the line density in this zipper strip region further.
Have again, in zipper strip of the present invention, configure the lines (lines that rugosity thin) less than the formation lines fiber number in formation second zipper strip main part region at the wale of the tooth installation portion with the first zipper strip main part area adjacency with the wale forming the first zipper strip main part region.Accordingly, can be formed more densely that configure tooth installation portion with wale that is the first zipper strip main part area adjacency and form the knit stitches in zipper strip region of wale in the first zipper strip main part region.
Therefore, it is possible to do not make the zipper strip thickness in this zipper strip region increase and improve zipper strip intensity and mar proof.Therefore, when forming chain tooth by injection molded or casting forming at tooth installation portion, can prevent this zipper strip region from sustaining damage because of the fastening of metal pattern, and prevent from more effectively producing fused mass leakage from the coil of tooth installation portion.
In addition, also have, in zipper strip of the present invention, the first zipper strip main part region is according to than when using zipper strip to constitute slide fastener, and the coil wale number being configured in the quantity of the wale on region (line) that the flange of pull head that forms this slide fastener passes through many is formed.
Such as, as above-mentioned patent document 3, when the second ~ four wale on the region that the flange being configured in pull head is passed through gets close to mutually, zipper strip intensity, the mar proof in the zipper strip region (flange passes through region) configuring the second ~ four wale can be improved.But, the wale interval between the 4th wale and the 5th wale than second ~ the wale interval of the 4th wale is wide.Therefore, exist between operating period along with slide fastener and increase, repeatedly carry out the slip of pull head, with the friction produced because of the slip of this pull head etc. for cause, 4th wale moves to the 5th wale side gradually, makes flange by the mar proof in region ageing ground situation about reducing.
On the other hand, by as the present invention, form the first zipper strip main part region according to the coil wale number that the quantity of the wale on the region passed through than the flange being configured in pull head is many, the zipper strip region that configure while wale can be got close to each other is formed wider by region than flange.
Therefore, even if increase between the operating period of slide fastener, repeatedly carry out the slip of pull head, the impact that the slip that the wale adjoined with the second zipper strip main part area side in the first zipper strip main part region is also difficult to be subject to pull head causes, even if increase between the operating period of slide fastener, also can prevent this wale from moving to the second zipper strip main part area side.In addition, even if such as move to the second zipper strip main part area side with the wale of this second zipper strip main part area adjacency, because this wale does not form flange by region, so, there is not the situation that the mar proof for the slip of pull head is reduced ageingly yet.

Namely, in the present embodiment 1, in the second laterally inserted line 34 be configured throughout the second wale W2 ~ the tenth three-winding stringer W13, the the second laterally inserted line 34 be inserted into leap second wale W2 ~ the 4th wale W4 is compared with the heat-shrinkable crossing over the second laterally inserted line 34 that tertiary coil stringer W3 ~ the 5th wale W5 is inserted into, and the heat-shrinkable of the beyond these two second laterally inserted line 34 is little.
In addition, in the present invention, the lines such as the laterally inserted line 34 of Trico litzendraht wire 32, second beyond the first laterally inserted line 33, the two second laterally inserted lines 34 specified and longitudinal insertion line 35 also can use the lines with heat-shrinkable.In this case, the dry-hot shrinkage of lines such as Trico litzendraht wire 32 grade is configured to less than the dry-hot shrinkage of above-mentioned first laterally inserted line 33, the two second laterally inserted lines 34 specified and longitudinal insertion line 35.
On the other hand, the knit stitches of tooth installation portion 11 is by being provided in the first and second wale W1, the chain type litzendraht wire 31 (0-1/1-0) of each of W2, cross over the first and second wale W1, a pair the 3rd laterally inserted lines 36 (2-2/0-0) of W2 configuration and the 4th laterally inserted line 37 (0-0/2-2), cross over second and tertiary coil stringer W2, the aforementioned Trico litzendraht wire 32 (1-2/1-0) of W3 configuration, the aforementioned first laterally inserted line 33 (0-0/3-3) be inserted into crossing over the second wale W2 ~ the 4th wale W4 tri-wale zigzags and the second laterally inserted line 34 (3-3/0-0) are formed.
In this case, the 3rd laterally inserted line 36 and the 4th laterally inserted line 37 make insertion position mutually walk crosswise the direction coil that staggers at coil in the mode of intersecting between walking crosswise at each coil to be inserted into walking crosswise.In addition, the 3rd laterally inserted line 36 is configured in zipper strip face side relative to core rope 15, and the 4th laterally inserted line 37 is configured in side inside zipper strip relative to core rope 15.Therefore, core rope 15 is clipped by the 3rd and the 4th laterally inserted line 36,37 in table the inside and is kept.
In addition, cross over the first and second laterally inserted line 33,34 that the second wale W2 ~ the 4th wale W4 is inserted into and possess heat-shrinkable as previously mentioned.In addition, although except the first and second laterally inserted line 33,34, the formation lines forming tooth installation portion 11 also can use the lines with heat-shrinkable, but, in this case, its dry-hot shrinkage is set to less than the dry-hot shrinkage of the above-mentioned first and second laterally inserted line 33,34.
Further, be configured in core rope 15 between the first wale W1 of tooth installation portion 11 and the second wale W2 to be incorporated into tooth installation portion 11 while carrying out the weaving into of zipper strip 10.This core rope 15 be inserted into the chain type litzendraht wire 31 that remains on and be configured at first and second wale W1, W2 and cross over that first and second wale W1, W2 be configured between the 3rd laterally inserted line 36 and the 4th laterally inserted line 37.
The knit stitches of the cloth edge 13 in the present embodiment 1 use be configured in the 12 and the tenth three-winding stringer W12, W13 the chain type litzendraht wire 31 (0-1/1-0) of each and be also configured in the aforesaid Trico litzendraht wire 32 (1-2/1-0) of zipper strip main part 12 and the second laterally inserted line 34 (3-3/0-0) and form.
In the zipper strip 10 of the present embodiment 1 with such knit stitches, the formation lines beyond the chain type litzendraht wire 31 being configured in cloth edge 13 (the 12 and the tenth three-winding stringer W12, W13) use the multifilament threads of nylon or polyesters.In this case, be configured in the chain type litzendraht wire 31 of the second wale W2 ~ the 5th wale W5, Trico litzendraht wire 32, first laterally inserted line 33, second laterally inserted line 34 and each lines (what comprise lines crosses over the lines that at least one row wale in the second wale W2 ~ the 5th wale W5 is inserted at least partially) longitudinally inserting line 35 use than formation second zipper strip main part region 12b formation lines (specifically, it is the chain type litzendraht wire 31 being only configured in the 6th wale W6 ~ the 11 wale W11, Trico litzendraht wire 32 and the second laterally inserted line 34 are (except leap the 4th and the 5th wale W4, lines beyond W5)) thin lines that fiber number is little.In addition, with regard to fiber number size comparatively speaking, can the line weight each other of measurement unit length compare, in this case, can using the lightweight lines little as fiber number.In addition, fiber number dtex (dtex) unit representation.
Accordingly, the flexibility of the second zipper strip main part region 12b can be guaranteed, and zipper strip thickness can not be made to increase by the knit stitches of densification formed throughout tooth installation portion 11 the second wale W2 adjoined with the first zipper strip main part region 12a and form the zipper strip region of tertiary coil stringer W3 ~ the 5th wale W5 of the first zipper strip main part region 12a.
In this case, be preferably configured in the chain type litzendraht wire 31 of the second wale W2 ~ the 5th wale W5, Trico litzendraht wire 32, the first laterally inserted line 34 of laterally inserted line 33, second as thin lines and longitudinally insert line 35 and use more than 56 dtexs (dtex) 300 dtexs (dtex) multifilament threads below.In addition, the chain type litzendraht wire 31, Trico litzendraht wire 32 and the second laterally inserted line 34 that are preferably only configured at the second zipper strip main part region 12b use more than 200 dtexs (dtex) 500 dtexs (dtex) multifilament threads below.
Further, in the zipper strip 10 of the present embodiment 1, the chain type litzendraht wire 31 being configured in cloth edge 13 (the 12 and the tenth three-winding stringer W12, W13) uses the recombination line with core sheath structure.The sheath portion of this recombination line uses the water-soluble synthetic resin of polyvinyl alcohol, core use use in zipper strip main part 12 as the nylon of fibrous material or the resin of polyesters.
If be immersed in warm water by such recombination line, then the water-soluble synthetic resin forming sheath portion is dissolved in water, finally only leaves the line forming the nylon of core or the thin of polyesters.Accordingly, more flexibly can be formed and configure the cloth edge 13 of this chain type litzendraht wire 31.In addition, in the present invention, as the chain type litzendraht wire 31 of water-soluble line being configured in cloth edge 13, except above-mentioned recombination line, also can use such as by a litzendraht wire of the independent lines be made up of water-soluble resin fiber and the independent lines doubling that is made up of common synthetic fibers.In addition, also the chain type litzendraht wire 31 being configured in the first wale W1 can be used as the independent lines be made up of water-soluble synthetic resin.
There is the zipper strip 10 of the present embodiment 1 of such knit stitches by core rope 15 being enrolled tooth installation portion 11 in one side, after one side has carried out weaving into, implement heat treatment, make the first laterally inserted line 34 of laterally inserted line 33, second possessing heat-shrinkable and the longitudinally insertion each lines of the line 35 significantly thermal contraction that are configured in the second wale W2 ~ the 5th wale W5.
Here, in heat treatment, carry out after this by the xeothermic process carried out of being heated by heater relative to the zipper strip be compiled to.In addition, owing to also heating this zipper strip when dyeing to zipper strip, so, also produce by this thermogenetic contraction.In this case, will heat in an atmosphere be defined as xeothermic, using the shrinkage factor under xeothermic as dry-hot shrinkage.
In addition, because the second laterally inserted line 34 crossing over the first zipper strip main part region 12a and the second zipper strip main part region 12b has the heat-shrinkable lower than the second laterally inserted line 34 being configured in the second wale W2 ~ the 5th wale W5, so, be interposed between the second wale W2 ~ the 5th wale W5 between the 5th wale W5 and the 6th wale W6 wider than the interval of adjacent wale.
In addition, linked by the litzendraht wire of both leap first zipper strip main part region 12a and the second zipper strip main part region 12b between the 5th wale W5 and the 6th wale W6.In addition, same, second wale W2 of tooth the installation portion 11 and tertiary coil stringer W3 of the first zipper strip main part region 12a is connected by the litzendraht wire crossing over both, and the 11 wale W11 of the second zipper strip main part region 12b and the tenth two coil stringer W12 of cloth edge 13 is connected by the litzendraht wire crossing over both.
Accordingly, second wale W2 ~ the 5th wale W5 is furthered to direction close to each other, each wale interval of the second wale W2 ~ the 5th wale W5 is by constriction, and the second wale W2 ~ the 5th wale W5 becomes state close to each other compared with the 6th wale W6 ~ the 11 wale W11 of formation second zipper strip main part region 12b.Meanwhile, due in the zipper strip region throughout the second wale W2 ~ the 5th wale W5, each coil walks crosswise interval also by constriction, so the size of the zipper strip length direction in this zipper strip region is shorter than the second zipper strip main part region 12b.
Therefore, in zipper strip 10 after heat treatment, the the second zipper strip main part region 12b be made up of the 6th wale W6 ~ the 11 wale W11 and by the 12 and the tenth the cloth edge 13 that forms of three-winding stringer W12, W13 there is suitable flexibility, simultaneously, due to high and formed densely throughout the zipper strip region line density of the second wale W2 ~ the 5th wale W5, so the zipper strip intensity in this zipper strip region improves.Have again, due to when using this zipper strip 10 to constitute slide fastener, fine and close throughout the zipper strip region of the second wale W2 ~ the 5th wale W5, so, can, as aftermentioned, make to improve (with reference to Fig. 4) relative to the mar proof of the slip of pull head 4.
Especially due to the second wale W2 in the present embodiment 1 ~ the 5th wale W5 as previously mentioned, use the lines less than the formation lines fiber number of formation second zipper strip main part region 12b, so, there is throughout the zipper strip region of the second wale W2 ~ the 5th wale W5 extremely fine and close knit stitches, more effectively can improve the zipper strip intensity in this zipper strip region.
And in the zipper strip 10 of the present embodiment 1, the high and zipper strip region that is that formed by the knit stitches of densification of line density is throughout the second wale W2 ~ the 5th wale W5 is formed wide.Therefore, even if flexibly form the second zipper strip main part region 12b, also can, across the first zipper strip main part region 12a, tooth installation portion 11 and the second zipper strip main part region 12b be left mutually, the knit stitches of tooth installation portion 11 is stablized.Therefore, as aftermentioned, when assembling chain tooth 2 to zipper strip 10, firmly stably chain tooth 2 can be anchored at tooth installation portion 11.
In addition, the zipper strip 10 of the present embodiment 1, by above-mentioned heat treatment, makes core rope 15, be configured in the second wale W2 ~ the first laterally inserted line 34 of laterally inserted line 33, second of the 5th wale W5 and longitudinally insert line 35 thermal contraction.Therefore, form after the heat treatment of this zipper strip 10 is that tooth installation portion 11 side of zipper strip 10 is shunk at zipper strip length direction relative to the zipper strip side edge part side (cloth edge 13 side) of its opposition side, and zipper strip 10 entirety becomes the state bent arciformly.
Relative to the zipper strip 10 of such the present embodiment 1, by chain tooth 2 is assemblied in tooth installation portion 11, zip strip 1 can be formed above.
In the present embodiment 1, such as, by the thermoplastic resin material such as tooth installation portion 11 injection molded polyformaldehyde, polypropylene, polybutylene terephthalate (PBT), nylon at zipper strip 10, formation chain tooth 2 manufactures zip strip 1 as shown in Figure 3.
When like this at chain tooth 2 plastic about zipper strip 10 injection molded of the present embodiment 1, to be applied with the state of the tensile force of regulation at the zipper strip length direction of zipper strip 10, sandwiched tooth installation portion 11 and the first zipper strip main part region 12a of zipper strip 10 by the upper die and lower die of injection mold assembly.And, by sandwich zipper strip 10 injection mold assembly chamber in high pressure injection-moulded melting resin, multiple chain teeth 2 with the shape of regulation are formed in the tooth installation portion 11 of zipper strip 10.
Now, in the zipper strip 10 of the present embodiment 1, the line density throughout the zipper strip region of the second wale W2 ~ the 5th wale W5 is high, and the knit stitches in this zipper strip region is formed densely.Therefore, even if under the state that zipper strip 10 is sandwiched by the upper die and lower die of metal pattern in the chamber of this metal pattern with high pressure injection-moulded melting resin, also can effectively prevent this melting resin from spilling outside chamber (fused mass leakage) through the coil of zipper strip 10, wale interval each other.
Accordingly, chain tooth 2 stably can be configured as the shape of regulation.In addition, owing to also can prevent melting resin from spilling zipper strip main part 12 at zipper strip 10, so, also do not exist after synthetic resin cooling, the situation of hard straightization of zipper strip main part 12.
In addition, at the lines that the zipper strip area configurations throughout the second wale W2 ~ the 5th wale W5 is thin, the zipper strip thickness in this zipper strip region can be made thin compared with the second zipper strip main part region 12b.Therefore, even if being injection molding metal mould for formation sandwiching throughout the second wale W2 ~ zipper strip region of the 5th wale W5 of zipper strip 10, the damage that also can as far as possible make this zipper strip region be subject to because of the pushing of metal pattern is little, can prevent the zipper strip intensity of zipper strip from reducing.
Further, as described above, the plastic chain tooth 2 of injection molded, when manufacturing zip strip 1, is assembled with the zipper strip 10 after chain tooth 2 and bends to globality arciform as described above.Its result is, using employ slide fastener that obtained zip strip 1 forms make fixing to the clothes etc. being mounted goods as slide fastener time, can prevent from forming at zipper strip 10, clothes such gauffer that rises and falls.
And, by making above-mentioned such zip strip manufactured 1 two be one group, and along the denture of these zip strip 1, pull head 4 being installed slidably, manufacturing slide fastener 3 as shown in Figure 4.In the slide fastener 3 obtained like this, the zipper strip intensity in the zipper strip region be made up of the second wale W2 ~ the 5th wale W5 is improved as described above.
Such as, general slide fastener is when receiving the horizontal pulling force pulled to the direction mutually left by the zipper strip of left and right, exist in zipper strip, be configured in the tooth installation portion that is assembled with chain tooth and be subject to the situation of the impact of very large horizontal pulling force by seam the first zipper strip main part region be contained between the second zipper strip main part region that the slide fasteners such as clothes are mounted on goods.
Under such circumstances, about in the slide fastener 3 of the present embodiment 1, because the zipper strip intensity of the first zipper strip main part region 12a be made up of tertiary coil stringer W3 ~ the 5th wale W5 is improved, so, even if slide fastener 3 is subject to horizontal pulling force, the problem that the generation of the formation lines of formation first zipper strip main part region 12a disconnects or the line that splits is so also effectively can be prevented.
Have again, in the zipper strip 10 of this slide fastener 3, be configured in flange on the region of the flange 4a being inserted with pull head 4 by region (when the present embodiment 1, the zipper strip region be made up of the second wale W2 ~ the 4th wale W4) as shown in Figure 4, be included in the zipper strip region of the second wale W2 formed densely with high line density ~ the 5th wale W5.
Like this, by region, there is high line density by the flange of zipper strip 10 to be formed densely, even if repeatedly carry out the slip of pull head 4, also can make with the friction between the flange 4a of pull head 4 and zipper strip 10 for cause, flange is disconnected by the formation lines in region, the line that splits be difficult to produce.
Further, about the zipper strip 10 of the present embodiment 1 line density is high and configured by the second wale W2 ~ the 5th wale W5 that region is wide throughout than flange by the zipper strip region formed densely.That is, the flange 4a of pull head 4 in the example shown in Figure 4, tertiary coil stringer W3 and the 4th wale W4 passes through.Therefore, in the present embodiment 1, by the 5th wale W5 to the first zipper strip main part region 12a, as wale interval narrow by the zipper strip region formed densely.
Therefore, even if increase between the operating period of slide fastener 3, repeatedly carry out the slip of pull head 4, the impact that the slip that the 5th wale W5 is also difficult to be subject to pull head 4 causes, there is not the 5th wale W5 to press close to the situation of the mode movement of the 6th wale W6 side.Therefore, there is not the situation for reducing pro rata between the mar proof of the slip of pull head 4 and the operating period of slide fastener 3 in the zipper strip 10 of the present embodiment 1, can use slide fastener 3 steadily in the long term.
In addition, in the present embodiment 1, by the tooth installation portion 11 injection molded synthetic resin material at zipper strip 10, form chain tooth 2 and form zip strip 1.But, about the zipper strip 10 of the present embodiment 1 also by the tooth installation portion 11 casting forming metal material at this zipper strip 10, can be formed chain tooth or form zip strip by riveting the metal chain tooth of installation at tooth installation portion 11.
Such as, passing through at zipper strip 10 casting forming metal material, when metal chain tooth 2 is anchored at zip strip 1 of tooth installation portion 11 by formation, same with the situation that injection molded synthetic resin material forms chain tooth 2, can prevent the metal of melting from spilling (fused mass leakage) through the coil of zipper strip 10, wale interval each other, in addition, also there is not molten metal and escape to zipper strip main part 12, make the situation of hard straightization of zipper strip main part 12.
Have again, even at casting forming metal material, when forming zip strip, even or by metal chain tooth riveted joint, when forming zip strip, also same with aforesaid situation, the zipper strip 10 chain tooth being installed to the zip strip of tooth installation portion 11 can have entirety and be bent to arciform form.
And be one group by the zip strip two of the riveted joint machining manufacture making the injection molded of metal material or metal chain tooth 2, form slide fastener, the zipper strip intensity that can obtain for horizontal pulling force is high, and the slide fastener of excellent in wear resistance for the slip of pull head 4.
